MCPCB-OS9735-10LIN : This Aluminium PCB is very flexible. It is designed to take 10 leds, and is designed for OSRAM Square series of 3x3mm Power Leds. The board layout is such that the 10 leds can be driven in
- Series(10 x 3v leds will equate to nominal 30V operation)
Non Direct Thermal Path : Dielectric under the thermal pad of LED
The MCPCB-OS9735-10LIN module requires careful attention to mounting and cooling to ensure that the junction temperature of the LED is kept well below the maximum rating as specified in the LED documentation published by Led Manufacturers
For optimal cooling, we recommend that the module be mounted to a suitable finned heat sink (aluminium or copper) that is exposed to open air. The module can be mounted to a heat sink in various ways
- 97 x 35 mm pressure sensitive, thermally conductive tape (Recommended)
- Thermal Compound: Requires the use of mechanical fasteners
Before fastening the module to the heat sink, ensure that the two mating surfaces are perfectly flat and clean in order to maximise heat transfer to the the sink.
Mechanical fasteners are recommended for this module.
The bottom of the LED MCPCB is electrically neutral, so it is not necessary to electrically isolate the base from the cooling surface.
Please note the use of Thermal Adhesives makes the PCB unlikely to be removed for servicing. Please consider this if removal of the board is desired as another TIM may be a better choice.
Optics Support: The board can accept small form optics.
Optics can be adhered to PCB with adhesive.
Assembly Guide for Optics: Ledil have a good generic guide on assembly of Leds/Optics, adhesives etc. Download
Termination: The ends of the PCB of has Anode and Cathode pads. The PCB can be standalone or wired in groups in Series or parallel.
